IMPROVEMENTIN HVDRANT AND PLUG VALVES.

Specification forming part of Letters Patent No. 194,973, datedSeptember '11, 1877; application =filed February 21, 1877. i

To all whom it may concern:

Be it known that I, THOMAS PHILLIPS, of St. Louis, inthe'countyofSt.Louis and State of Missouri, have invented an Improved Hydrant and PlugValve, of which the following is a specification:

This invention is an improved hydrantvalve; also serviceable as aplug-valve.

The novel features constituting'my improvements are as will hereinafterappear, and be pointed out in' the claims.

Of the drawings, Figure 1 is a sectional elevation of the boxing andside elevation of the valve parts inside said boxing. Fig. 2 is anenlarged sectional elevation to showconstruction of lower boxing andcontained valve parts that are hidden in the ground. Fig. 3 is a topplan, showingupper valve which controls the waste, and the peculiarconstruction of the cap or cover is also indicated. Fig. 4 is a faceview of the lower valve.

A is theshellor lower chamber, in which the water first collects beforeit is discharged. A is the inlet-pipe connecting to the lower part of A.(See Figs. 1 and 2.) The shell A, further, has the female screw-threadat a, (see Fig. 2,) for the purpose of receiving the threads of the capor cover.

In order to secure the lower chamber A, I cast the same so as to have onits lower face lugs a, (see Fig. 2,) which branch from its sides, andcan be secured to a suitable foundation, X.

To protect and also additionally secure the shell A, I surround iteither with a wood or iron casing, B. This is made to have-openings b inline with the lugs 11.. (See Fig. 2.) Said casing B is united to X byangle-irons I). (See Fig. l.) The casing B can be made to cover thehydrant post or boxing, the object in using said casing being to protectthe boxing from rotting, and also protect the parts of the hydrant thatremain in the ground.

The parts above described, according to the nature of my invention, arethose that permanently remain in the ground-that is, they are not dugout for the purpose of repairing,

removing, or replacing the operating parts; and by the latter term Imean all the parts embraced in the description now following.

0 is the cap or cover. (See Figs. 1 and 2.) The lower part, 0, of thecap has the male threads at c to engage the female threads a of theshell, (see Fig. 2,) and it is this screw featureyopera'ted from withoutor from the top by means of the hydrant boxingor post,that enables me toremove or replace, as the case may require, the upper sectional parts'(viz.,

, carried by the cap 0) from the lower sectional parts that, as stated,remain in the ground.

The under face of the cap 0 is the valveseat. It has one-or morewater-passages, c, communicating from the lower waterchamber to theinterior of the cap, which constitutes the upper or dischargechamber D.'(See Fig. 2.) The top of the cap (or outside "of th'e discharge-chamberD) in construction is made to have the opposite lugs 01 and the curvedbody part (1 and, lastly, the shoulder at "01 (See Figs. 1, 2, 3.)

The lugs 01 serve as a hearing or hold-fast for the boxing to engage sothat by means of the latter the turning movement can be made to screw orunscrew the sectional parts. Also,

said lugs d serve to limit the turning movement of the crank-rod.

The top face 01 of the body part d is a valve-seat. The sides of saidbody part serve also as a guide for the operation of the valve top ofthe seat 01 At d one or more wastepassages are made. (See Fig. 2.)

E is the lower valve that controls the passages c-'5. e., to open orshut the hydrant or plug-valve. Said valve is a circular plate,corresponding to the seat, and has water-passages c in line with thoseof the cap. a is the valve-packing. It is retained by projecting pointsand bearing-edges 0 formed on the face of said valve. (See Figs. 2, 4..)

The valve E with packing is secured to the lower end of the rod F. Thelatter, for this purpose, has its end made square-shaped, like theopening made in the valve, (see Fig. 4,) and the joint made secure by anut, 0'. (See Fig. 2.)

The rod F also carries the upper valve G that controls the waste. Thevalve G I make of the constructive shape shown in Fig. 3- that is, witha part of its circle left away to form the two edges at 9. (See Figs. 1,3.) The part so left away is in accordance with the part rotary movementthe operating parts perform. The edges 9 will then abut against the discharge-pipe, this latter serving to estop the operating parts, toindicate the full opening and closing of the hydrant or valve.

9 isthe valve-packing, shaped like the valve, and properly securedthereto. Further, the valve G has one or more passages, 9 (see Figs. 2,3,) in line with the waste at, before mentioned, and so that when bothpassages d and g are in line the waste is open otherwise to be shut.

g are pins projecting from the valve G, and engaging the sides of thebody part d, (see Fig. 1,) and serve to guide the valve in itsoperation.

To secure the valve G with its packing on the rod F, this latter is madeU-shaped, (see Fig. 3,) fitted to pass through the like opening shapedin the valve. By this joint the turning movement of the rod carries saidvalve with it.

At f is a packing contained in an annularrecess, (see Fig. 2,) renderingthe joint at that place water-tight.

G is a spring round the rod. The lower end of the spring is held againstthe top of the valve G, while the upper end of the spring is secured bya nut, 9 (See Figs. 1, 2.) The spring G serves to hold the lower valveup to its seat, and the upper valve down to its seat.

H is the discharge-pipe, joined in communication with one end of thedischarge-chamber D. (See Figs. 1 and 2.) The nozzle H of the pipe H canbe screwed on or off.

Iis the part or boxing which is inserted down on the cap 0. The loweredge of the boxing I has mortised openings 2', (see Figs. 1 and 3,)which are in line with the lugs d of the cap, and so that said boxingcan hold fast to said lugs, and so that by turning the said boxing tothe right or left the operating parts carried by the cap 0 can be unitedor disengaged from the parts that remain hidden in the ground. The loweredge of the boxing I rests upon the shoulder d of the cap. At t theboxing I has an offset, so that it can rest on top of the casing B. (SeeFig. 1.) I is the top for the boxing. The rod F passes through said top,and is turned from without by a hand-crank.

The parts being thus constructed and arranged, their operation is asfollows: Turn the rod F until it is estopped. The hydrant or valve, wewill say, is then open. This open condition consists in the lower valveE having its openings brought in line with those that communicate withthe discharge-chamber D. The discharge of water will then take placefrom D out of H. The hydrant is open, therefore, when waste is closed,and, vice versa, the waste is oven when hydrant is shut 0E.

By reversing the operating-rod F the upper valve has its openingsbrought in line with the waste, while the lower valve is made to closethe communication of water to the dischargechamber D. The waste thenfreely escapes, and that out of the discharge-pipe, and therefore I gainthe great advantage of an antifreezing hydrant or plug valve.

I have shown one or more waste-openings also, one or more water-passagesleading to the discharge-chamber; the object being to provide adequatemeans to obtain a complete discharge of the waste and a full pressuredischarge.

The arrangement of the operating parts here shown is such as to beprotected in the greatest measure from the action of the water andwater-pressure.

The lower valve is always retained to its seat, the pressure from belowinsuring this end also, while the spring sufficiently retains the uppervalve down on its seat.

In case of repairs being necessary, turn the boxingIso as to unscrew thesections, and the cap with all the operatingparts-rviz., lower valve,lower casing, packing, the rod, upper valve, its packing, the,discharge-pipe and box ingcan all be lifted out of the ground withoutdigging. Thus all essential parts liable to require repairs can bedisconnected and removed and replaceda feature which, to the fullextent, as here shown, has not heretofore been achieved.

What I claim is- 1. The valve E, having bearing edges and points 0 tosecure its packing.

2. The valve E, having water-passages c, the packing e, the rod F, thecap or cover 0, having the upper water-chamber D and lower part 0, theshell A, having inlet A, all said parts being combined and operating tocontrol the inlet of water to said chamber D, as and for the purpose setforth.
